髓质型食管癌的X线表现与放疗预后的关系

目的:探讨髓质型食管癌的X线表现与放射敏感性及预后的关系.方法:分析1990年4月～1994年12月期间接受放射治疗的134例髓质型食管癌的X线表现和随访结果,全部病人采用~(60)Cor线外照射DT48-52Gy,其中 58例于外照射结束时增加～(192)Ir后装治疗1～2次,将X线片上其病变段上端或下端有外翻表现的病例定为外翻型,上下端无外翻表现定为非外翻型.结果:外翻型在近期疗效、生存情况方面优于非外翻型(P<0.05),在COX模型多因素分析中它与锁骨上淋巴结转移情况一起对生存时间产生影响.结论:髓质型食管癌的X线表现不同,其放射敏感性及预后也不同,它可作为放疗前预后因素的判断指标之一.

The ralationship between the esophagraphy and prognosis of esophageal carcinoma

To study the prognosis of esophageal carcinoma by radiotherapy. Methods: 134 patiens from Apr 1990 toDec 1994 were treated with 50Gy by 60Co,58patiens of them were added with 192Ir afterloading treatment, l0Gy to 14Gy in two weeks after 60Co treament. According to the esophagraphy, we divide the patiens into two shapes, the retroflextion type,that the end of the sick section is retroflextion;the incline type, that the end of the sick section is of incline. The recent curative effect and survive time of the retroflextion was better than the incline(P<0. 05). Results:Many factors which include age, length, posi-tion, lymphatic transfer, shapes in esophagraphy, and 192Ir afterloading were analyzed by Cox model. Conclusion: The result shows that only lymphatic transfer and shapes in esophagraphy are correlated with survive time.
